What is the advantage to have a function or procedure created inside another function or procedure?

Hello Guys,

This is an example:

procedure SumAllValue: Integer;
	   Function Sum_A_B(a, b : integer): Integer;

	  My code here calls the Sum_A_B(x,y)

Open in new window

Is there any advantage using that way? Or would it be better to have it in a unit library or even create it for all my unit?

Is it only concept?

BY having it inside the procedure, you are limiting the visibility to the function to that procedure.

You can only use it inside SumAllValue
